Which is the correct formula of Freon-12?a)CCl2F2b)CClF3c)CHCl2Fd)CCl3...
There is formula for it .....

no of carbon atom -1
no of hydrogen+1
no of fluorine atom

see
CCl2F2

1-1=0 {C}
0+1=1{H}
2{F}

Cl is not included in this formula ,it is only for the digit 12 (no of H and then F)

so option A is freon -12
see a example- CCl3F

no of carbon atom (1)-1=0
no of hydrogen atom (0)+1=1
no of fluorine atom (1)=1

it is freon -11 (by no of hydrogen atom and fluorine atom)

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The existence of coordination compounds with the same formula but different arrangements of the ligands was crucial in the development of coordination chemistry. Two or more compounds with the same formula but different arrangements of the atoms are called isomers. Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties. There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers. There are two main forms of isomerism: structural isomerism and stereoisomerism. The different chemical formulas in structural isomers are caused either by a difference in what ligands are bonded to the central atoms or how the individual ligands are bonded to the central atoms.The following questions are multiple choice questions. Choose the most appropriate answer:Q. Which of the following complexes show linkage isomerism?
